What can be used to prevent the displacement of a rubber dam clamp?

A ligature tied to the clamp serves as a reliable method to prevent its displacement during dental procedures. This technique involves securing the clamp with dental floss or a similar material, which provides additional stability. The ligature acts as a safeguard against the forces that could otherwise cause the clamp to slip or fall off, particularly during the placement or adjustment of the rubber dam.

The other options, while they may attempt to address clamp stability, do not directly address the issue of displacement as effectively. Using thicker rubber dam material might provide a better fit and reduce tearing, but it does not specifically secure the clamp. The application of more adhesive could enhance the bond between the clamp and the tooth, yet it doesn’t guarantee that the clamp won’t be displaced by movement or suction. Applying dental wax around the clamp might help with comfort or provide a smooth surface, but it also does not offer a solution for immobilizing the clamp itself. Thus, tying a ligature to the clamp is the most effective and practical method for ensuring the clamp remains in place.
